Abstract: A transfer case includes a primary output shaft, a secondary output shaft, a clutch, and a hub. The clutch includes a plurality of interleaved plates for selectively rotationally coupling the primary output shaft to the secondary output shaft. The hub rotationally couples the primary output shaft and the clutch. The hub includes an outer annular member and an inner annular member. The inner annular member is rotatable within the outer annular member for the hub to selectively release oil into the clutch.

Abstract: A transfer case comprises a primary output shaft, a secondary output shaft, a clutch, and a plurality of valves. The primary output shaft includes a hub rotationally coupled thereto. The clutch is selectively couples the primary output shaft to the secondary output shaft to transfer torque therebetween. The clutch includes a housing, interleaved plates, and an apply plate. The housing is rotationally coupled to the secondary output shaft. The interleaved plates alternate between a first subset of the interleaved plates rotationally coupled to the hub, and a second subset of the interleaved plates rotationally coupled to the housing. The apply plate compresses the interleaved plates for transferring torque between the hub and the housing. The valves selectively release oil supplied through the primary output shaft into the housing. Each valve includes a bore formed in the hub and a valve rod movable by the apply plate to open the valve.
